title = "Numerical analysis of improvement effects on peaty ground by vertical drains/vacuum consolidation based on a new macro-element method",
abstract = "Large deformation has been usually observed in peaty ground due to embankment loading. To increase stability and reduce residual settlement, ground improvement prior to the construction is very important. This study investigated numerically the ground improvement effects of vertical drain/vacuum consolidation on a peaty ground possessing a risk of slip failure under the non-improvement condition. A new macro-element method considering unknownwater pressure in drainswas incorporated in a soil-water coupled finite deformation analysis code GEOASIA. Analysis results showed that the ground improvement by PVDs is effective to prevent a failure during loading. Additionally, it was revealed that the PVDs installation with a sufficiently small drain pitch could have almost the same effect as the combination with vacuum consolidation to reduce the residual settlement after the construction. Vacuum consolidation is the most effective method to reduce the surrounding upheaval and lateral displacement due to the inward deformation by vacuum pressure.",
